I wouldn't hold your breath (although I wish them luck). There are however a bunch of low cost high performance RV64 chips coming this year and next from China that will change things dramatically. (I'm a Fedora/RISC-V maintainer, and I'm in Beijing today and tomorrow talking to RISC-V people. It's 23:57 here, got to go to bed :-/ )
Do you know what companies are making them? I'd love to take a closer look as I've also been looking for a risc-v rpi alternative.
As is always the way with these things, unfortunately I'm under an NDA until the products are released. However I can tell you the rather obvious thing: We're helping them to understand how to get changes they need integrated into upstream communities (kernel, GCC, binutils, uboot in particular) so that their hardware will boot without patching when or soon after it is released.
